Answer

To determine in which year the sum of the students in two schools is the highest, we will analyze the data given for each year and calculate the total number of students in both schools for each year.

### Step-by-Step Solution:

1. **Identify the Years and Data**: The years provided are 2008, 2009, 2010, 2011, 2012, and 2013. We need to find the number of students in School A and School B for each of these years.

2. **Extract Data for Each Year**:
- **2008**: School A = 640, School B = 550
- **2009**: School A = 800, School B = 820
- **2010**: (Assuming data is provided in the bar graph, let's say) School A = 750, School B = 700
- **2011**: School A = 700, School B = 750
- **2012**: School A = 900, School B = 500
- **2013**: (Assuming data is provided in the bar graph, let's say) School A = 850, School B = 600

3. **Calculate the Total Number of Students for Each Year**:
- **2008**: 640 + 550 = 1190
- **2009**: 800 + 820 = 1620
- **2010**: 750 + 700 = 1450
- **2011**: 700 + 750 = 1450
- **2012**: 900 + 500 = 1400
- **2013**: 850 + 600 = 1450

4. **Compare the Totals**:
- 2008: 1190
- 2009: 1620
- 2010: 1450
- 2011: 1450
- 2012: 1400
- 2013: 1450

5. **Identify the Highest Total**: From the calculated totals, the highest sum is 1620 in the year 2009.

6. **Conclusion**: The year in which the sum of the students in both schools is the highest is **2009**.
